STREET-CROSSIN G SIGN AL.

Application led September 1916.

d To au fis/'wm zt may oom-ern Be it known that I, WILLIAM E. Calin, a citizen of the United States, and a resident of Seattle, in the eounty of King and State of Washington, have invented certain new and useful Improvements in Street-Crossing Signals, of which the following is a full, true, and exact specification.l

My invention relates to street crossing signals and has for its principal object to provide a traliic signal for street crossings which embodies means for displayin printed instructions to tralic; to provife means for rapidly changin the device so as to display a diderent set o printed instructions. Air other object of my device is to provide a series of independently operated visible Word signals for traffic moving in two o1- more directions at cross streets. In the conj trol of street trailie at intersections of busy 4thoroughfares it is customary to have a traf iid officer at stneet intersections who controls the traffic in all directions by some form of signal. My device is designed to be suported from over-head wires at the intersec? vlions of the streets and to `be controlled from a convenient point on the curb line, thus ob- Viating the necessity of the trallic oilicer standing in the center of the street inter sections. While my device as shown coini bines the signaling mean; for traffic in all four directions in one pieife of apparatus, it will be understood that separate sections of my device may be used independently on eaeh eorner of the street intersection.

Other objects will appear as my invention is more fully explained in the following specifications, illustrated in the accompanying drawing and pointed out in the appended claim.

In the drawings Figure 1 is a plan view of my device with parts broken away and duplioate parts omitted. Fig. 2 is a side elevation of same with parts broken away. Fig. 3 is a diagrammatic plan illustrating alternative operating mechanism.

Referring more particularly to the drawings, numeral l indlcates square top and hotA tom: frames `whioh are opencentrally :nid which are `tied together in parallel relationship with corner posts 2. Intermediate the corner posts 2 and the frames' 1 a series of trianguhnvanos 3 are pivotally mounted to frames l. The vanos 3 are so positioned Speoication of Letters Patent.

and arranged with impl-rl lo ein-h other als to he easily thrown into line so lhnl ono luce of each of thorn lios in a eonnnon plane und, they are easily revolved until another svt of faces are brought into a ronnnon plane. The vanes ill'Istrated in Fig. l show those on the left and side as beingv arranged so that one face of each vane lies in :1 connnon plane. ln this position a word or other instruetions is printed upon the exposed faces of the vanos. Other words or instructions may bo printed upon the adjacent faces of the vanos so that when they :ire revolved :l neuv sot. olf instructions are risible. and the p11-.rionsy sel is hidden from view. The runes Il on oooh side ol' frames l are pivoled to :L eonnnon bar -l so that they may he quickly revolved to a new position by a. lengthwise movement of the bar fi. The vanos shown to the right of l are in a nent-ral position; 4lhal is, they are not displaying any signals as nono of their fares are thrown into a ronnnon plane. The signals are left in this position at .night or when not in operation. Solenoid magnets 5 are provided one adjacent either end of each har l and have their foros con nerted by incuns of links ti to bars el. The function of the solenoids is to operate the connected vanos upon oarh side ol the frana-.s l. It is advantageous lo have omh side operal'e independently upon the` roi-nor` whirh haviriir lines which tizrn the oorner as in this` caso it is lrwpu'nlly desirable lo lot a Certain lino oi' trzllliv on one` side olH thi` street proceed whihl ilnvs on lho other sido oi' thul street are held up. M v device is preferably covered with a roof 7 which ovorhangs the vain-s and shields lightingglobes 8 which are used aft/cr night. Each of the vanes- 25 are provided with si op lips il which hold the various vanos in each battery in proper :ilineinent when their faces are thrown into a connnon plano .lud further close tho slight. gap Infineon lho variousv vanos. This is an important and novel feature of luy device.
